Foundation Underpinning - Repair Sunken Foundations

If you have sunken foundations that result in cracked floors and walls, pavements or driveways, we can fix it!

We have a trustworthy and responsible approach to addressing sunken foundations that result in cracked walls, floors and concrete slabs.

Raising and re-levelling sunken foundations with polyurethane is highly effective and efficient, but it requires the expertise to select the right injection points and the knowledge to inject to the correct depth and quantity. It also requires proven, standardised resins that guarantee consistent results in the long term – decades into the future.

Drawing on over 60 years’ experience, Resinject raise and re-level sunken foundations, cracked walls and subsiding floors in houses. We re-level factory and workshop floors, bridge approach slabs, runways, roads, driveways, footpaths and mining foundations.

We work from a self-contained truck, using twin pumps with extended hoses. We only use our proprietary resins, tested to Australian Standards. And, needless to say, we are licensed builders.

For dependable, lasting results, you should ask for nothing less.

We service NSW, ACT/SOUTHERN and QLD.

What are the guarantees of your product?

Drawing on over 60 years’ combined experience, Resinject only use an Australian Standard resin and inject to a depth of up to 3.5 metres if necessary. We also provide plenty of support around each lift point. This is why we can confidently guarantee our product against significant settlement for a full 50 years.

Why does it take a licenced builder to carry out a site assessment?

Only a licenced builder has the knowledge and experience required to assess how a building’s internal structure is going to react to ground consolidation and stabilisation.

How deep into the ground do you inject?

Injection depth can be critical to ensuring long-term ground consolidation. Each situation varies and the injection depth is determined by the state of the ground. That’s why we inject our resin at multiple and different depths varying between 800mm and 3.5m.

Do you have to park on my property?

Our crew will arrive in a self contained truck, when planning road access, our work truck is approximately 8.0m long, 2.5m wide and 3.2m tall. Due to our long hoses we can work up to 70 metres from our self-contained mobile unit, so there should be no need to park any heavy vehicle in a sensitive area.
